3.8 The height, length and width of the floor are 4.7 and 2.75 respectively. How to calculate two steps?

The design of 3.8m three-run stairs on the ground floor: the total number of steps is 24 (8 steps for each run), the step length× width× height is1.325m× 28.57cm×15.83cm, and the two rest platforms have the same size of 2.75m× 1m, the first rest platform. Three-run stairs with a height of 3.6m on the second floor: the total number of steps is 23 (8 steps for the first run and the second run and 7 steps for the last run), the stair step length is× width× height1.325m× 28.57cm×15.65cm, and the size of the rest platform is 2.75m×1m. ? Note: Due to the difference in floor height, the tread height on the second floor will be 0.18cm lower than that on the first floor (15.83-15.65), which is almost negligible. When the formwork is supported on the second floor, the top platform should be increased by 28.57cm to ensure the same pedal width.
